About# Creating a custom plastic case is now easier than ever with Snap Circuits by Elenco. Kids can learn about electronics in an engaging way, and with a 3D printer, you can expand the available components by creating your own unique designs. Snap Circuits by Elenco https://amzn.to/2zYI7tT Updates# A new version of the 1x3 is currently being worked on. This updated design features larger tabs and component holes that are closer together, making it easier to solder everything in place and fit the cover on properly. Testing of the new version has begun, and a 3x3 version for an 8 pin IC socket and a 1x3x3 for a 3 pin potentiometer are also being developed. Printing# When printing the base and cover pieces, it is recommended to print without supports or raft. However, using a raft can provide additional stability. Assembly# To assemble your Snap Circuit case, start by printing a base and a cover piece. Next, attach snaps to both the base and cover by placing one part of the snap on the outside and another on the inside, then crimping them together with a snap tool. Thread component leads through the holes in the cover and bend them towards the inside of the cover snaps. Use a short length of solid 22 or 24 gauge wire to connect the component lead to both the top cover snaps and base snaps. To solder the wires to the cover snaps, crimp a little "V" into the wire so that a portion sits inside the snap's cavity. Solder the component lead to one end of this wire while the other will be soldered to the base snap. Cut the wire so you have just enough to keep the base and cover open enough to solder and to reach the base snaps. To solder the wire to the base snaps, use a center punch to make a divot and then drill a hole, thread the wire into the hole and solder in place. Place the cover on the base. This may require a shim of some sort to pry the sides open enough for the small tabs on the sides of the covers to fit into the mount holes on the base. 12mm Snaps https://amzn.to/2PWeOTx Snap Tool https://amzn.to/2HT6ptE Notes# Do not use the above capacitor as it is intended for comedic purposes only and poses a danger to children.
